Abstract
The utility model discloses a collet chuck base fixing device used for machining a bearing wheel hub. The collet chuck base fixing device used for machining the bearing wheel hub comprises a fixing device. The fixing device comprises a collet chuck, a base and an end cap, wherein the collet chuck is arranged on the base, the end cap is arranged at the right end of the base and is matched with the collet chuck, a collet chuck fixing screw is arranged at a lateral portion of the base, two end cap fixing screws are arranged at the right end of the base, a chip-removing groove, a positioning groove and a workpiece groove are formed in the collet chuck, the chip-removing groove is arranged in the middle of the collet chuck, the positioning groove is arranged at the tail portion of the collet chuck, and the workpiece groove is arranged at the top of the collet chuck. The collet chuck base fixing device used for machining the bearing wheel hub is simple in structure, better enlarges the contacting area between a workpiece to be machined and the fixing device, prevents the workpiece from slipping, reduces the scrap rate of products, improves stability, prolongs operation time, and saves cost.
Description
Technical field
The utility model relates to a kind of fixture, is specifically related to a kind of collet chuck base fixture for the machining bearing wheel hub.
Background technology
The upper bearing (metal) car A face of machining bearing, bore internal diameter, the installation way of external diameter/finish turning internal diameter external diameter/these 3 operations of boring is all to be to adopt claw clamping wheel hub external diameter to process, but blank wheel hub external diameter is the band tapering, contact-making surface is smaller during with claw clamping wheel hub external diameter, when processing work, easily cause workpiece to skid, thereby cause processing scrapping of workpiece, and when changing planes kind, change chuck and claw approximately about 2 hours, cause the operating time long, inefficiency, poor product quality.
The utility model content
The purpose of this utility model is to provide a kind of collet chuck base fixture for the machining bearing wheel hub, and the contact area of increase and processing work is increased work efficiency and product quality.
For realizing this purpose, the utility model has adopted following technical scheme:
A kind of collet chuck base fixture for the machining bearing wheel hub, comprise fixture, described fixture comprises collet chuck, base and end cap, described collet chuck is located at described base, described end cap is located at described base right-hand member, described end cap and described collet chuck coupling, described base leans to one side to be provided with a collet chuck fixed screw, described base right-hand member is provided with two end cap fixed screws, described collet chuck is provided with chip area, locating slot and a workpiece groove, described chip area is located in the middle of the described collet chuck, and described locating slot is located at described collet chuck afterbody, and described locating slot is corresponding with described collet chuck fixed screw, and described workpiece groove is located at described collet chuck top.
Further, the groove width of described chip area is 12mm.
Further, the groove width of described locating slot is 8mm.
Further, be provided with in the workpiece groove in the described collet chuck and be no less than an anti-slip tank.
Preferably, described anti-slip tank comprises horizontal anti-slip tank and vertical anti-slip tank.
The utility model contrast prior art has following advantage: simple in structure, better enlarge the contact area of workpiece and fixture, and prevent that workpiece from skidding, reduce product rejection rate, improve stability and operating time, the saving cost.

The specific embodiment
Referring now to accompanying drawing, further describe the utility model.
Extremely shown in Figure 6 as Fig. 1, a kind of collet chuck base fixture for the machining bearing wheel hub, comprise fixture, fixture comprises collet chuck 1, base 2 and end cap 3, collet chuck 1 is located at base 2, end cap 3 is located at base 2 right-hand members, end cap 3 and collet chuck 1 coupling, base 2 leans to one side to be provided with a collet chuck fixed screw 11, and base 2 right-hand members are provided with two end cap fixed screws 31, and collet chuck 1 is provided with chip area 12, locating slot 13 and a workpiece groove 14, chip area 12 is located in the middle of the collet chuck 1, locating slot 13 is located at collet chuck 1 afterbody, and locating slot 13 is corresponding with collet chuck fixed screw 11, and workpiece groove 14 is located at collet chuck 1 top.
In order better to carry out chip removal, this practical new novel in, the groove width of chip area 12 is 12mm, the groove width of locating slot 13 is 8mm.
In order to prevent that work in-process workpiece 4 from skidding, be provided with in the workpiece groove 14 in the collet chuck 1 and be no less than an anti-slip tank 15, anti-slip tank 15 comprises horizontal anti-slip tank 151 and vertical anti-slip tank 152, workpiece groove 14 in the collet chuck 1 has angle, thereby when collet chuck 1 is clamping can with workpiece 4 close-fittings, prevent that workpiece 4 from skidding, the number of anti-slip tank can arrange according to producing voluntarily.
In process of manufacture, usually the Heat Treatment Control of this fixture is at HRC50-55 °, in order better to control the clamping degree of workpiece, the collet chuck top is 120 ° of sub-assemblies that are equally divided into three structure unanimities, two two form three slits between three sub-assemblies, width≤the 2mm in slit, the utility model is when work, after operating personnel were fixing with end cap 3, the workpiece groove 14 that workpiece 4 is inserted in the collet chucks 1 was when pull bar 5 during toward post-tensioning, collet chuck 1 is toward post-tensioning conveniently, three movable sub-assembly slits on collet chuck 1 top diminish, thereby the workpiece groove 14 of collet chuck 1 is diminished, thus clamping work pieces 4.
Above-described the utility model embodiment does not constitute the restriction to the utility model protection domain.Any modification of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
